A reduced fat cookie contains 12g of fat per serving. In order for food to be termed reduced fat it must have at least 20% less fat than the regular item. What can you conclude about how much fat is in a serving of the regular cookie?
12g/(0.8) = 15 grams of fat in a regular cookie.
(The 0.8 comes from taking 100% - 20%)
